In the 1970s, Hong Kong’s rapacious landlords try to evict 72 tenants but sworn brothers Ha Kung (Eric Tsang) and Shek Kin (Jacky Cheung) helped the group of 72 defeat the landlord and landlady and coincidentally rescue Siu To Hung (Anita Yuen) from a planned forced marriage. When both sworn brothers fall for Siu To Hung and propose to her, she flips a coin and Ha wins her hand in marriage. The sworn brothers become sworn enemies and Shek’s hatred fuels intense rivalry against Ha in business dealings. They continue to clash in 2010 and are in competition in the busiest street in the city, which is still home to the 72 tenants.,
